Legacy Data Extraction

Read your mainframe without rewriting it.

We modernize things like mainframe data without affecting the core data using SLMs. We sit alongside your system of record — COBOL, AS/400, DB2, EDI, fixed-width tapes, scanned PDFs — and pull the fields your modern apps actually need.

What's included

The whole vertical slice, not a fragment.

3 sections

What we read

Every format still running in production, including the ones nobody wants to touch.

  • COBOL, RPG, AS/400, DB2, VSAM record layouts
  • Fixed-width, EBCDIC, EDI X12 / EDIFACT
  • Scanned PDFs and TIFFs via OCR + SLM
  • Green-screen terminal session parsing

How it ships

Field-level outputs that drop into the systems you already run.

  • JSON / Parquet to your warehouse or lake
  • Streaming records to Kafka, Kinesis, or pub/sub
  • Validated against your golden record when one exists
  • Replayable runs against historical archives

What we never do

The system of record stays untouched. Always.

  • No writes back to the mainframe
  • No schema changes to source systems
  • No vendor lock-in — you own the pipeline
  • No data leaves your perimeter without approval
How we work

Three steps. No surprises.

  1. 01

    Inventory

    Two weeks. We read your source, document every format, and produce a written map of the data.

  2. 02

    Build

    Four to six weeks. We train the SLM on your real records, ship the pipeline, and validate against ground truth.

  3. 03

    Run

    Hand-off to your team with runbooks, monitoring, and an upgrade path. We stay on retainer.
